Abstract
A dynamic gain equalizer-monitor (DGEM) includes a light modulator operable to modulate one or more component wavelengths of an input optical signal. The DGEM also includes a grating operable to receive one or more modulated component wavelengths from the light modulator. The grating is also operable to combine a first portion of each of the one or more modulated component wavelengths and transmit that first portion into an output optical signal. The DGEM may also include a detector array operable to receive, from the grating, a second portion of modulated component wavelengths that are separated from the first portion by the grating. The detector array is operable to generate an electrical signal proportional to an optical characteristic associated with each of the modulated component wavelengths of the second portion.
